Hello I have two pictures with some questions Id like to get answers to! Short and great explanations please thank you !

Please Explain the answer,Thanks

Thermodynamics Please READ THE PROBLEM! I’m tired of posting the same problem over and over. please Read. This is what the asking for please: -1. sketch and label all your answers on the nozzle -2. Sketch and label all your answers on the process on a P-V diagram.... Thank you

Solve question 2 based on the answer of question 1.  You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil and used 516 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating. Natural gas BTU:  1,028 Btu per cubic foot Oil BTU: 138,590 Btu per gallon   Natural Gas BTU= 80,698,000  Oil BTU                = 71,512,440    The home that used a natural gas furnace used more energy for heating. 2.- You need a new furnace for your home, and you are comparing systems that use natural gas and heating oil. One factor to consider is the cost of the fuel. You can compare the price of the fuels on an equal basis by dividing the price per unit of the fuels by the Btu content per unit of the fuels to get a price per million Btu. Assume Natural gas price = $10.50 per thousand cubic…

Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed.  Background information of Ethanol: Boiling Point = 78 0C Melting Point = -114 0C Starting Temperature = -120 0C After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. After eight more minutes, it begins to boil. It boils for six minutes. Heat is added for two more minutes until ethanol reaches 80 0C. Label “melting” where this takes place. Label “vaporization” where this takes place. Label “phase change” where a phase change occurs. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS. Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.

Cathy Gwynn for a class project is analyzing a "Quick Shop" grocery store. The store emphasizes quick service, a limited assortment of grocery items, and higher prices. Cathy wants to see if the store hours (currently 0600 to 0100) can be changed to make the store more profitable. Time Period Daily Sales in the Time Period 0600-0700 $40 0700-0800 70 0800-0900 120 0900-1200 400 1200-1500 450 1500-1800 500 1800-2000 600 2000-2200 200 2200-2300 50 2300-2400 85 2400-0100 40 The cost ofthe groceries sold averages 65% of sales. The incremental cost to keep the store open, including the clerk's wage and other operating costs, is S23 per hour. To maximize profit, when should the store be opened, and when should it be closed?

How is thermal energy lost when a person exits a building through an exterior door in the winter? a) Description of your level of confidence in the variable values. b) The overall level of confidence in the solution and why. Just need answers for these two questions ?

Simple Machines-Levers, Inclined Planes, and Pulleys Directions: Use the appropriate equation to answer the following questions. All answers should be recorded below or in your Engineering Design journal. Remember to show all work. A lever has an effort arm that is 5 meters long and a resistance (load) arm that is 3.5 meters long. How much effort is needed to lift a 100 Newton weight? 5K i). Draw the figure representing the problem ii). How much effort is needed to lift a 100 Newton weight? iii). What is the Actual Mechanical Advantage 1. 5m i) AOON 5-5m

Quality has been defined as customer satisfaction (or "fitness for use"). Quality can also be defined as "conformance to specifications". In theory, if you create the right specifications and then manufacture a product that meets these specifications, you should achieve customer satisfaction.  Consider the following four scenarios for a particular product: A) Conforms to specifications and is competitive in its adequacy.   B) Conforms to specifications and is not competitive in its suitability.    C) It does not conform to specifications and is competitive in its education.   D) Does not conform to specifications and is not competitive in its education.   Which of these are not, in theory, feasible, but in practice occur and cause a lot of conceptual confusion?  Can you cite some examples?

Q1: Who does what in organizations Based on this scenario only, what employer obligations to workers are likely to have been contravened? Note: You should support your answer, where applicable, using relevant information from the scenario

Engineering Economy A company has determined the price and the monthly demand of its products are related by the equation D = √775 - p, where p is the price per unit in dollar and D, is the monthly demand. The associated fixed costs are $2,125 per month and the variable costs are $100/ unit. Use this information to answer the following: a)What is the optimal number of units that should be produced and sold each month? b) What is the maximum profit? c)Determine the value of D that represents the break-even point?

You have two toys with two different shapes; one is shaped like a solid cylinder and the other like a solid sphere. The two toys have the same volume (V(cylinder) = V(sphere)) and same radius (R(cylinder)=R(sphere)). They both generate the same total heat (q(cylinder)=q(sphere)) and are made from the same material (k(cylinder)=k(sphere)). a) Determine whether the sphere toy or the cylinder toy has the higher heat flux anywhere in the toy b) Calculate the ratio of the maximum heat fluxes between them Hint: Assume the ends of the cylinder toy to be perfectly insulated.

Last person got every single question wrong and didn't include units. Please help.

Both part please Please show your work and explanation for each question.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

Which of the following statements is correct? O Manufactured capital represents industrial capacity, institutions, roads, built environment, financial wealth (GDP). Human capital represents clean atmosphere, fresh water, fertile land, productive oceans, accessible minerals, and fossil energy. Natural capital represents health, education, skills, technical expertise, accumulated knowledge, happiness. Strong sustainability is growth in two of the three capitals, weak sustainability is all capitals are diminished. O Manufactured capital represents clean atmosphere, fresh water, fertile land, productive oceans, accessible minerals, and fossil energy. Human capital represents health, education, skills, technical expertise, accumulated knowledge, happiness. Natural capital represents industrial capacity, institutions, roads, built environment, financial wealth (GDP). Strong sustainability is growth in two of the three capitals, weak sustainability is the capitals are unaffected. O…
